Letters Patent No. 114,568, dated May 9, 18.71.

IMPROVEMENT IN SAW-MILLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, SIMON KEMPER, of Berger, in thecounty of Franklin and Stateof Missouri, have made a certain new and useful improved-Horizontal Saw-Mill; and I do hereby declare that the following is a full and true description thereof, reference being bad to the accompanying drawing and to the letters of reference marked thereon.

This invention relates First, to the arrangement of a sliding saw-frame with saw operating horizontally;

, Secondly, to theconstruction and arrangement of parts by which the saw can be adjusted to saw any required thickness; I

Thirdly, in providing the carriage with adjustable dogs for clamping the log or lumber securely in position; and- Lastly, to certain detail construction of. parts now to be more fully described.

To enable those skilled in the art to make and use my said invention, I will now more fully describe the same, referring to the accompanying Figure 1 as a top plan; to

Figure 2 as a longitudinal sectional elevation; to

Figure 3 as a front elevation; and to Figure 4 as a rear elevation.

The stationary frame or bed A I provide with a carriage, B.

The carriage B consists of a longitudinal rack, B, to which the head-blocks B B are secured, and upon whiclrthe log or timber is placed.

1 The head-block's are provided with wheels,'b b b b, so as to slide evenly upon the iron track of the bed A, in manner usual.

' In order that the log can be securely and firmly held I have arranged between each head-block a crankscrew, 0, supported at one end in proper bearings c.

Said screw carries a sliding dog, 0, moving in elongated slots 0 0 fig. 2.

Also, said head-blocks have a series of vertical slots or grooves, 0 fig. l, in which the dog 0 is inserted. Thus all sizes of logs can be clutched and held in place;

The feed-motion is imparted to the carriage B by its rack B meshing in pinions D on the end of the feed-shaft D, said shaft being operated byits gear D meshing with pinion d on the lower shaft d of frame A The arrangement of driving-wheels, cone-pulleys, and feed-works, with their belting-connections for regulating the feed and imparting the feed-motion to the carriage B, is made in the usual well-known manner to be operated by horse or steam power.

To the main frame A I secure the uprightframe E, supporting the adj ustable frame carrying saw-frame and saw, as follows:

Within. the frame E I arrange the frame F, working on guide-plates cc, and supported and receiv ng its vertical movement by racks f f meshingin pinlons f f on shaft G, which has its bearings secured to the frame E, as shown in fig. 4.

To adjust the frame F in any required verticalposition I provide the end of shaft with aproper gearwheel, G, gearing with pinion g on a shaft having its hearings on the side of frame E, and which carries the hand-wheel H, as shown in figs. 3 and 4.

By turning the hand-wheel H the frame F receives its vertical slide-motion, and, when adjusted as required, is secured in position by a pawl, It, engaging in gear-wheel G. The saw-frame J consists of upper and center beams J J, its saw K being secured to arms jj, and set to operate horizontally.

The beams J J 2 of saw-frame I provide with slides It It, fitted to slide and operate in the grooved slides It is, secured to the adjustable frame F, in manner clearly shown in fig. 2.- r

The saw and its frame are thus supported on frame F. They receivetheir horizontal reciprocating motion by a pitmau, L, pivoted at l to the saw-frame J, and connecting with and secured to the fly-wheel on main driving-shaft operated by the power source.

As, therefore, saw-frame, with saw, rests in. the slides of the adjustable frame F, it can readily be ad justed to sawany thickness required. This ad ustmeut of the saw, it will be observed, can readlly be accomplished as soon as the carriage starts to teed, and without stopping the motive power. Furthermore, as the log when once clamped in its true position need not be changed, the operation of sawing can be accomplished with great accuracy, and with a saving of great time and labor.

Having thus fully described my said invention,

What I claim is- 1. The crank-screw G, slicing and removable dogs 0 0, when arranged in head-blocks B B of a feedcarriage, B, asand for the purpose described.

2. The combination of the horizontal saw K, its

frame J having slides Is -7c arranged to slide in groovedslides I: It of the adjustable frame F, substantially as set forth.

In testimony of said invention I have hereunto set my hand inpresence of witnesses.

Witnesses: SIMON KEMPER.
